Water Heater Services

This is one of the most common questions we get, and the honest answer is — it depends on your household. Traditional tank water heaters are reliable, affordable upfront, and work well for most homes. They store 40 to 75 gallons of pre-heated water and are straightforward to install and maintain.

Tankless systems, on the other hand, heat water on demand so you never run out. They take up far less space, last nearly twice as long as tank units, and can reduce your energy bills by 20 to 30 percent over time. The trade-off is a higher upfront cost and potentially more involved installation — especially if your home needs gas line or venting upgrades.

For homeowners considering tankless water heater installation in Ontario, CA, we'll walk you through the pros and cons based on your home's layout, your family size, and your budget. Whether you go tank or tankless, Regal Plumbing handles the entire job from start to finish — including permits and code compliance in Fontana and Upland.

Southern California has some of the hardest water in the country, and that takes a real toll on your water heater. Over time, calcium and mineral deposits build up inside the tank, coating the heating elements and reducing efficiency. This forces the unit to work harder, driving up your energy bills and shortening its lifespan by several years.

If you're dealing with frequent water heater repair in Ontario, CA, hard water is likely a contributing factor. Annual flushing helps, but the most effective long-term solution is pairing your water heater with a water filtration or softener system. It protects your water heater, your pipes, and your fixtures — and it pays for itself over time in fewer repairs and lower utility costs.
